Watch This: Beyoncé HBO Doc Teaser

"I always battle with how much do I reveal about myself," Beyoncé says in the narration to an HBO documentary, set to premiere in February.

In this clip, she doesn't reveal much besides that sentiment, reflections on dealing with fear and a so-quick-you-might-miss-it shot of the baby bump that became Blue Ivy. But it will no doubt be enough to create some excitement among fans eager for the more personal look at the very private star that the special promises.
